Chapter 6 Tutorials

MES3500-24/24F User’s Guide

The settings are completed now. If you miss some settings above, subscriber C could not 
successfully receive an IP address assigned by the PPPoE Server. If this happens, make sure you 
follow the steps exactly in this tutorial.

This tutorial shows you how to shut down a port when:

• there is a loop occurred

or

• too many ARP requests (over 100 packets per second) received on a port

You also want the Switch to wait for a period of time (10 minutes) before resuming the port 
automatically, after the problem(s) are gone. Loop guard and Errdiable features are helpful for this 
demand.

Note: Refer to 

 for more 

information about Loop Guard and Errdiable.

To configure the settings:

First, click Advanced Application > Loop Guard. Select the Active option in the first section to 
enable loop guard on the Switch. Then select the Active option of the first entry (port *) to enable 
loop guard for all ports. Click Apply.
